Deodorant compositions containing 1,2-hexanediol

ABSTRACT

The present invention is directed to deodorant compositions, and methods of using such compositions, wherein the compositions comprise from about 0.1% to about 99.9% by weight of a deodorant active, fragrance or combination thereof, and from about 0.1% to about 99.9% by weight of a carrier comprising 1,2-hexanediol. The deodorant composition preferably further comprises a suitable gellant or structurant to provide the desired product form, including a deodorant gel solid stick. The 1,2-hexanediol carrier is a highly effective coupling agent and is milder to the skin when applied topically to the axilla or other areas of the skin as compared to many other polyol-containing deodorant compositions. The present invention also relates to the use of triclosan/triclocarban combinations for improved deodorant efficacy.

FIELD OF INVENTION

This invention relates to deodorant compositions comprising deodorantactive and a carrier comprising 1,2-hexanediol. This carrier is milderto the skin than many other polyol-containing carriers, and isespecially effective as a coupling agent for gellant systems containingsilicone or other carriers. The compositions provide improved clarity,and therefore include clear or translucent deodorant compositions.

BACKGROUND OF THE INVENTION

Deodorant compositions are well known for use in controlling malodorsassociated with human perspiration. These malodors develop from humanperspiration primarily as the result of microbial interaction with sweatgland secretions which then produces pungent fatty acids. Deodorantcompositions contain antimicrobial agents to help control the microbialdevelopment of such malodors, and/or they can contain deodorizingfragrances that help to mask the sensory perception of the malodors.

Deodorant compositions in gel form are especially popular as a means forpreventing or masking malodor arising from perspiration. These geldeodorants compositions are typically in the form of a solid or softsolid stick and, like other deodorant products, are also appliedtopically to the underarm or other area of the skin. The gel deodorantstypically contain a gellant or other structurant, a solvent tosolubilize the gellant or other structurant, and a deodorant active suchas an antimicrobial active, deodorizing fragrance or other odor maskingmaterial. These compositions may be aqueous or anhydrous systems, andtypically contain a polar solvent to help solubilize the gellant orother structurant. Many of these compositions also contain diol or otherpolyhydric solvents such as aliphatic polyhydric alcohols having from 2to 12 carbon atoms, common examples of which include propylene glycol,ethylene glycol, diethylene glycol, 1,2-proplyene glycol, 1,3-propyleneglycol, 1,3-butylene glycol (1,3-butane-diol), glycerine(1,2,3-trihydroxy propane), 2-methyl-2,4-pentane-diol (hexylene glycol),2-ethyl- 1,3-hexane-diol, 1,2,6-hexanetriol, and combinations thereof.

Many deodorant compositions, however, cause skin irritation whentopically applied to the underarms or other sensitive areas of the skin.This irritation is attributed primarily to the diol or polyhydricsolvents commonly used in such compositions. This skin irritation isespecially problematic when the applied composition is an anhydroussystem containing higher concentrations of the polyhydric carrier, andeven more problematic in a small percentage of the population that isunusually sensitive to topical polyol irritation.

It has now been found that deodorant compositions containing1,2-hexanediol cause less skin irritation than many other deodorantcompositions containing diol or other highly polar polyol solvents. Ithas also been found that 1,2-hexanediol is an excellent coupling agentthat not only causes less skin irritation, but can also be used at lowerconcentrations than many other coupling agents which further results inreduced skin irritation. The 1,2-hexanediol solvent is also very usefulin formulating clear or translucent deodorant compositions.

It has also been found that deodorant compositions containing acombination of triclosan and triclocarban provides the composition withimproved deodorant efficacy. This combination of actives may be used inany topical composition, including the compositions described herein.

It is therefore an object of the present invention to provide adeodorant composition and a method of using such a composition that ismilder to the skin than other diol-containing deodorant compositions. Itis a further object to provide such a composition that also has goodskin feel characteristics during and after topical application, and/orprovides improved product clarity.

SUMMARY OF THE INVENTION

The present invention is directed to deodorant compositions comprisingfrom about 0.1% to about 99.9% by weight of deodorant active and fromabout 0.1% to about 99.9% by weight of a carrier comprising1,2-hexanediol. The compositions may be aqueous or anhydrous. Preferredembodiments comprise a gellant or other suitable structurant.

The present invention is also directed to a method of controlling orinhibiting malodor associated with human perspiration, which methodcomprises the step of applying to the axilla area of the skin from about0.1 gram to about 2.0 gram of the deodorant composition defined herein,wherein the deodorant composition comprises about 0.1% to about 99.9% byweight of deodorant active, deodorizing fragrance or combinationthereof, and from about 0.1% to about 99.9% by weight of a carriercomprising 1,2-hexanediol, or wherein the deodorant compositioncomprises a combination of triclocarban and triclosan.

It has now been found that the selection of 1,2-hexanediol as a solventor coupling agent in an deodorant composition provides the compositionwith improved performance relative to other polyol-containing deodorantcompositions. In particular, 1,2-hexanediol has been found to be milderto the skin than many other similar polyol-containing solvents, and ismore effective as a coupling agent than many other commonly used diolsolvents, and/or provides improved product clarity. These compositionsalso provide improved skin feel performance, aesthetics, and/or productstability as compared to many other polyol-containing deodorantcompositions.

It has also been found that the combination of triclosan andtriclocarban when applied topically to the axilla or other area of theskin provides improved deodorant efficacy that is greater than theadditive deodorant benefits that would otherwise be expected from such acombination. The triclosan/triclocarban combination is effective inproviding for improved deodorant performance from the deodorantcomposition of the present invention, or when applied from any othertopical deodorant composition that contains this active combination andthat is otherwise suitable for application to human skin.

Method of Manufacture

The compositions of the present invention may be made by any of themethods known in the art for formulating deodorant compositions, orwhich are otherwise effective in formulating such compositions. As willbe apparent to those skilled in the art, the particular method will bedependent upon the selection of the specific types and amounts of thecomponents employed, as well as the final product form desired, e.g.,liquid, solid sticks, soft solids, creams, lotions, single or multiplephase systems containing solid or dissolved active, suspensions orsolutions, clear or translucent or opaque, etc.

In general, the deodorant compositions of the present invention can beprepared by merely combining the liquid carrier with the deodorantactive. Optional gellants or structurants may then be added withagitation and heat to a temperature of from about 75° C. to about 100°C. to allow the gellant or structurant to melt and form a substantiallyclear or translucent liquid. The resulting solution is cooled beforeadding fragrance (if applicable), and then the cooled composition ispoured into an appropriate container or dispenser at about 70° C. andallowed to solidify within the container or dispenser by cooling orallowing to cool the contained composition to ambient temperature.

Method For Use

The deodorant composition of the present invention may be used as anintermediate in formulating other deodorant compositions, or it may beformulated in final form to be topically applied to the axilla or otherarea of the skin in any known or otherwise effective method forcontrolling malodor associated with perspiration. These methods compriseapplying to the axilla or other area of the human skin a safe andeffective amount of the deodorant composition of the present invention.In this context, the term "safe and effective amount" means an amount ofthe deodorant composition topically applied to the skin which iseffective in inhibiting or minimizing or masking perspiration malodor atthe site of application while also being safe for human use at areasonable risk/benefit ratio. In this context, a safe and effectiveamount typically ranges from about 0.1 gram per axilla to about 2.0 gramper axilla. The compositions are preferably applied to the axilla orother area of the skin one or more times daily, preferably once daily.
